Before riding through deep mud or
sand, deflate your tires slightly to increase the
tire’s footprint and provide better traction.
Deflated tires will decrease your ground clearance
though. Remember to re-inflate your tires before
going on-road again.Use a steady momentum to carry
you through. Keep your speed up and use higher
gears. Don't spin your tires, and don't stop till
you're out of the deep mud or sand. If your wheels
start to spin, ease off the throttle just a bit and
allow the tires to slow down and regain traction.
